Background: The radial artery (RA) is often utilized for diagnostic coronary angiography and percutaneous intervention. Recent high-level evidence supports RA use in preference to the saphenous vein as a conduit for coronary revascularization. Aim: To demonstrate gross and histologic changes of the RA following transradial (TR) access. Methods: We present two patients who had open RA harvest for coronary bypass surgery after TR catheterization. Results: Examination 8 years after TR catheterization demonstrated thickened intima and dissection, and examination 12 years following TR catheterization with percutaneous coronary intervention demonstrated chronic dissection with thickened intima and near occlusion of the lumen. Conclusion: TR access via the RA, even after several years, is associated with significant injury, making it unusable as a conduit for surgical coronary revascularization. A RA that has been utilized for catheterization should not be considered for coronary revascularization.
